For example, if an exemption is given because the peak rate of reduction of 50% for the two year storm cannot be met, the selected project may address reducing the orifice size at an existing stormwater management basin. |
As another example, if an exemption is given because the removal of 80% of the Total Suspended Solids cannot be met, the selected project may provide a natural vegetated buffer around a lake edge to discourage the geese population and address water quality impacts due to fecal impairment. |

For example, if an exemption is given because the peak rate of reduction of 50% for the two year storm cannot be met, the selected project may address reducing the orifice size at an existing stormwater management basin. |
As another example, if an exemption is given because the removal of 80% of the Total Suspended Solids cannot be met, the selected project may provide a natural vegetated buffer around a lake edge to discourage the geese population and address water quality impacts due to fecal impairment. |
